Carrier-of-Carriers IPv4 VPNs
A carrier-of-carriers VPN is a two-tiered relationship between a provider carrier and
a customer carrier. In a carrier-of-carriers VPN, the provider carrier provides a VPN
backbone network for the customer carrier (Tier 1). The customer carrier, in turn,
provides layer 3 VPN or Internet services to its end customers (Tier 2).
This section provides the background you need to understand carrier-of-carriers VPNs
in general, but deals with IPv4 VPNs. For information about carrier-of-carriers IPv6
VPNs, see "Carrier-of-Carriers IPv6 VPNs" on page 469 .
The carrier-of-carriers VPN enables the customer carrier to provide the following
services for its end customers:
host1(config)#virtual-router pe1
host1:pe1(config)#access-list dot-one permit 0.0.0.1 255.255.255.0
host1:pe1(config)#route-map globxmap1
host1:pe1(config-route-map)#match ip address dot-one
host1:pe1(config-route-map)#set local-pref 200
host1:pe1(config-route-map)#exit
host1:pe1(config)#ip vrf pe11
host1:pe1(config-vrf)#rd 100:1
host1:pe1(config-vrf)# route-target both 100:1
host1:pe1(config-vrf)#global export map globxmap1
host1:pe1(config-vrf)#exit
Traditional IP services The customer carrier provides Internet connections for
its customers and uses the provider carrier's VPN to connect its dispersed
networks.
Layer 3 VPN services The customer carrier provides VPN services for its
customers and uses the provider carrier's VPN for the backbone that connects
the customer carrier's VPN sites. This environment is called a hierarchical VPN,
